wont boot with second card

[Mcfool123]

Just added a second 670 to the rig for gaming in windows and now mac won't boot figured something like this would happen any one know how to fix this. Preference would be without having to remove the second card to get it working but if need be ill take it out.

P.S. will probably being doing a clean install for maverick so will have no problem if it something that would cause loss of data not to mention all data is on hdd not boot ssd

The only one that I see that may be causing the problem is the Graphics Mode line

Well did the old add lion kexts for the faster boot up and now its is working fine and booting in less then 5 seconds again guess that was all that it was and hopefully it is fixed in mavericks
